Nguwuphi umahluko phakathi kwe-vector signal kunye ne-rf yomqondiso?

Umthombo womqondiso unokubonelela ngemiqondiso echanekileyo kwaye eqingqiweyo kakhulu kwizicelo ezahlukeneyo kunye nezicelo zovavanyo lwenkqubo. Umthengisi womqondiso wongeza umsebenzi wemozulu, onokukunceda ukulinganisa i-System System kwaye wenze uvavanyo lwentsebenzo. Zombini i-vector sisayina kunye nomthombo we-RF umyili unokusetyenziswa njengomthombo wovavanyo lovavanyo. Apha ngezantsi sineempawu zabo phantsi kohlalutyo.
Nguwuphi umahluko phakathi kwe-vector signal kunye ne-rf yomqondiso?
1. Intshayelelo kumthombo we-vector
Umthengisi we-vector isiginali wavela nge-1980s, kwaye wasebenzisa indlela ephakathi ye-vector vector ye-vector vector edibene nendlela yokudityaniswa kwerediyo ye-proroquency phantsi kwendlela yokuvelisa i-vector. Umgaqo kukusebenzisa iyunithi ye-frequency synthesis ukuvelisa i-microwale yendawo eqhubekayo ye-Oscillator ye-Oscillator kunye ne-frequency eqhelekileyo. Umqondiso ophakathi ophakathi kunye nesayini ye-Baseband Faka i-vector modulator ukuvelisa i-vector ephakathi ye-vecture ye-vector ene-verthency ye-veer enesantya esisigxina soMyinzi we-REPREAL. uphawu. Isayini yerediyo yerediyo iqulethe ulwazi lwe-baseband olufanayo njengombandela ophakathi we-vector vecture. I-RF sisayina i-Syreyil-signali kwaye imohlwayo yiyunithi yokupaka umqondiso, emva koko ithunyelwe kwizibuko lokuphuma.

I-vector signal Rinerator Rinerator Runerherator Synthesic Synthesis, indawo yokubonisa umqondiso, inkqubo yokuhambisa i-Analog kunye nezinye iinkalo ezifanayo nomthengisi oqhelekileyo oqhelekileyo. Umahluko phakathi komthengisi we-vector kunye nomthengisi oqhelekileyo womqondiso yiyunithi yemodyuli ye-vector kunye neyunithi ye-Baseband Storem.

Njengeemodi ze-alog, indalo yedijithali ineendlela ezintathu ezisisiseko, ezizezi zemodyuli, iMoulf Codround kunye nemo yemodyuli ye-frequency. Imodyuli ye-vector ihlala inamacandelo amane asebenzayo emine: I-Oscillator yendawo ye-90 ° I-Shif-Shif-Sputhing Preming Preminaint iguqula imiqondiso ye-rf ye-RF; Iiyunithi ezimbini zemixube ziguqula i-Baseband Sy-Sign Shring kunye ne-quadratural maild kunye ne-RF ehambelana ne-RF ngokulandelelana; Iyunithi yamandla eSynthesi ishwankathela le miqondiso mibini emva kokuphindaphinda kunye nokuphuma. Ngokubanzi, zonke izibuko kunye nemveliso yemveliso zimiswa ngaphakathi kumthwalo wama-50 owenziweyo kwaye yamkele indawo yokuqhuba eyahlukileyo yokunciphisa ukuncipha kwemveliso yezibuko kunye nokuphucula ukusebenza kweMpumelelo yeVector.

ICandelo leSiseko leSitayile lisetyenziselwa ukuvelisa i-Insul efunekayo ye-Insul eqondakalayo, kwaye i-waveform enikezwe ngumsebenzisi nayo inokukhutshelwa kwimemori yemowudi yokuvelisa umsebenzisi. Umthengisi we-Basebal genel ufumana iprosesa ye-Basebal iqulethe iprosesa ye-BROS, umvelisi wedatha, umvelisi wemiqondiso, i-firsel ye-firsel ye-filser

2. Ukwaziswa komthombo we-RF
Itekhnoloji yeRenthesing yanamhlanje ihlala isebenzisa indlela ye-synthesi engathanga ngqo yokuqhagamshela imvano-mithombo yobuqhetseba kunye nerejista yoMthombo weRekhodi yeSigaba esivaliweyo. Ifuna izixhobo ze-hardware, ukuthembeka okuphezulu, kunye noluhlu oluxhaphakileyo. Isiseko sayo sisiseko esitshixelweyo, kunye nomthombo we-RF umyili ngumxholo obanzi we-spectrum. Ngokubanzi, nawuphi na umthombo ongumqondiso onokuthi uvelise umqondiso we-RF unokukhwela umthombo we-RF. Imithombo yolwazi ye-vector yangoku ikakhulu kwibhendi ye-RF, ke yona ibizwa ngokuba yimithombo ye-vector rf.

Okwesithathu, umahluko phakathi kwemiqondiso emibini
I-1. Umthombo wophawu ongumqondiso ongumqondiso werediyo kuphela usetyenziselwa ukuvelisa i-Alog Ralog Ralog Readres, kwaye ayisetyenziswanga ukuvelisa imiqondiso yemowudi, ngakumbi imiqondiso yemo yemodyuli yedijithali. Olu hlobo lomthombo wophawu ngokubanzi lunebhendi engaphakathi kunye noluhlu olukhulu lwamandla.

2. Umthombo we-vector umthombo usetyenziswa ikakhulu ukuvelisa imiqondiso ye-veccring, oko kukuthi, i-shorial moduals yonxibelelwano lwedijithali, i-TSK, i-TSK, i-TSK, i-TSK, i-HSM / I-TDDE, i-TDDMAE, i-TDDMA YE-TDDE, iWimax? Neminye imigangatho. Kumthombo we-vector umthombo, ngenxa yemodulator yangaphakathi yangaphakathi, i-frequency ngokubanzi ayiphezulu kakhulu (malunga ne-6gz). Isalathiso esihambelanayo somthambo sayo (njengebhendi eyakhiweyo ye-Base-in Basebol) kunye nenani leendlela zesiginali yisalathiso esibalulekileyo.
